Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139404, here are decompositions:

7 + 139397 = 139404
11 + 139393 = 139404
17 + 139387 = 139404
37 + 139367 = 139404
43 + 139361 = 139404
61 + 139343 = 139404
71 + 139333 = 139404
101 + 139303 = 139404

Showing the first eight; more decompositions exist.
